+ * Structures defining a network interface, providing a packet
+ * transport mechanism (ala level 0 of the PUP protocols).
+ *
+ * Each interface accepts output datagrams of a specified maximum
+ * length, and provides higher level routines with input datagrams
+ * received from its medium.
+ *
+ * Output occurs when the routine if_output is called, with three parameters:
+ *	(*ifp->if_output)(ifp, m, dst, rt)
+ * Here m is the mbuf chain to be sent and dst is the destination address.
+ * The output routine encapsulates the supplied datagram if necessary,
+ * and then transmits it on its medium.
+ *
+ * On input, each interface unwraps the data received by it, and either
+ * places it on the input queue of a internetwork datagram routine
+ * and posts the associated software interrupt, or passes the datagram to a raw
+ * packet input routine.
+ *
+ * Routines exist for locating interfaces by their addresses
+ * or for locating a interface on a certain network, as well as more general
+ * routing and gateway routines maintaining information used to locate
+ * interfaces.  These routines live in the files if.c and route.c

+ * OpenBSD:        xs     x      x
+ *
+ * - ifa_ifwithaf()
+ *   bsdi[34], netbsd, and openbsd define it in sys/net/if.c
+ *   freebsd (all versions) does not have it.
+ *  
+ * - struct rt_addrinfo
+ *   bsdi4, netbsd 1.5R and beyond: rti_addrs, rti_info[], rti_flags, rti_ifa,
+ *	rti_ifp, and rti_rtm.
+ *   others: rti_addrs and rti_info[] only.
+ *
+ * - ifa->ifa_rtrequest
+ *   bsdi4, netbsd 1.5R and beyond: rt_addrinfo *
+ *   others: sockaddr * (note that sys/net/route.c:rtrequest() has an unsafe
+ *	typecast code, from 4.3BSD-reno)
+ *
+ * - side effects of rtrequest{,1}(RTM_DELETE)
+ *	BSDI[34]: delete all cloned routes underneath the route.
+ *	FreeBSD[234]: delete all protocol-cloned routes underneath the route.
+ *		      note that cloned routes from an interface direct route
+ *		      still remain.
+ *	NetBSD: 1.5 have no side effects.  KAME/netbsd15, and post-1.5R, have
+ *		the same effects as of BSDI.
+ *	OpenBSD: have no side effects.  KAME/openbsd has the same effects as
+ *		of BSDI (the change is not merged - yet).
+ *
+ * - privileged process
+ *	NetBSD, FreeBSD 3
+ *		struct proc *p;
+ *		if (p && !suser(p->p_ucred, &p->p_acflag))
+ *			privileged;
+ *	FreeBSD 4
+ *		struct proc *p;
+ *		if (p && !suser(p))
+ *			privileged;
+ *	FreeBSD 5
+ *		struct thread *td;
+ *		if (suser(td))
+ *			privileged;
+ *	OpenBSD, BSDI [34], FreeBSD 2
+ *		struct socket *so;
+ *		if (so->so_state & SS_PRIV)
+ *			privileged;
+ * - foo_control
+ *	NetBSD, FreeBSD 3
+ *		needs to give struct proc * as argument
+ *	OpenBSD, BSDI [34], FreeBSD 2
+ *		do not need struct proc *
+ *
+ * - bpf:
+ *	OpenBSD, NetBSD 1.5, BSDI [34]
+ *		need caddr_t * (= if_bpf **) and struct ifnet *
+ *	FreeBSD 2, FreeBSD 3, NetBSD post-1.5N
+ *		need only struct ifnet * as argument
+ *
+ * - struct ifnet
+ *			use queue.h?	member names	if name
+ *			---		---		---
+ *	FreeBSD 2	no		old standard	if_name+unit
+ *	FreeBSD 3	yes		strange		if_name+unit
+ *	OpenBSD		yes		standard	if_xname
+ *	NetBSD		yes		standard	if_xname
+ *	BSDI [34]	no		old standard	if_name+unit
+ *
+ * - usrreq
+ *	NetBSD, OpenBSD, BSDI [34], FreeBSD 2
+ *		single function with PRU_xx, arguments are mbuf
+ *	FreeBSD 3
+ *		separates functions, non-mbuf arguments
+ *
+ * - {set,get}sockopt
+ *	NetBSD, OpenBSD, BSDI [34], FreeBSD 2
+ *		manipulation based on mbuf
+ *	FreeBSD 3
+ *		non-mbuf manipulation using sooptcopy{in,out}()
+ *
+ * - timeout() and untimeout()
+ *	NetBSD 1.4.x, OpenBSD, BSDI [34], FreeBSD 2
+ *		timeout() is a void function
+ *	FreeBSD 3
+ *		timeout() is non-void, must keep returned value for untimeout()
+ *		callout_xx is also available (sys/callout.h)
+ *	NetBSD 1.5
+ *		timeout() is obsoleted, use callout_xx (sys/callout.h)
+ *	OpenBSD 2.8
+ *		timeout_{add,set,del} is encouraged (sys/timeout.h)
+ *
+ * - kernel internal time structure
+ *	FreeBSD 2, NetBSD, OpenBSD, BSD/OS
+ *		mono_time.tv_u?sec, time.tv_u?sec
+ *	FreeBSD [34]
+ *		time_second
+ *	if you need portability, #ifdef out FreeBSD[34], or use microtime(&tv)
+ *	then touch tv.tv_sec (note: microtime is an expensive operation).
+ *
+ * - sysctl
+ *	NetBSD, OpenBSD
+ *		foo_sysctl()
+ *	BSDI [34]
+ *		foo_sysctl() but with different style.  sysctl_int_arr() takes
+ *		care of most of the cases.
+ *	FreeBSD
+ *		linker hack.  however, there are freebsd version differences
+ *		(how wonderful!).
+ *		on FreeBSD[23] function arg #define includes paren.
+ *			int foo SYSCTL_HANDLER_ARGS;
+ *		on FreeBSD4, function arg #define does not include paren.
+ *			int foo(SYSCTL_HANDLER_ARGS);
+ *		on some versions, forward reference to the tree is okay.
+ *		on some versions, you need SYSCTL_DECL().  you need things
+ *		like this.
+ *			#ifdef SYSCTL_DECL
+ *			SYSCTL_DECL(net_inet_ip6);
+ *			#endif
+ *		it is hard to share functions between freebsd and non-freebsd.
+ *
+ * - if_ioctl
+ *	NetBSD, FreeBSD 3, BSDI [34]
+ *		2nd argument is u_long cmd
+ *	FreeBSD 2
+ *		2nd argument is int cmd
+ *
+ * - if attach routines
+ *	NetBSD
+ *		void xxattach(int);
+ *	FreeBSD 2, FreeBSD 3
+ *		void xxattach(void *);
+ *		PSEUDO_SET(xxattach, if_xx);
+ *
+ * - ovbcopy()
+ *	in NetBSD 1.4 or later, ovbcopy() is not supplied in the kernel.
+ *	we have updated sys/systm.h to include declaration.
+ *
+ * - splnet()
+ *	NetBSD 1.4 or later requires splsoftnet().
+ *	other operating systems use splnet().
+ *
+ * - splimp()
+ *	NetBSD-current (2001/4/13): use splnet() in network, splvm() in vm.
+ *	other operating systems: use splimp().
+ *
+ * - dtom()
+ *	NEVER USE IT!
+ *
+ * - struct ifnet for loopback interface
+ *	BSDI3: struct ifnet loif;
+ *	BSDI4: struct ifnet *loifp;
+ *	NetBSD, OpenBSD 2.8, FreeBSD2: struct ifnet loif[NLOOP];
+ *	OpenBSD 2.9: struct ifnet *lo0ifp;
+ *
+ *	odd thing is that many of them refers loif as ifnet *loif,
+ *	not loif[NLOOP], from outside of if_loop.c.
+ *
+ * - number of bpf pseudo devices
+ *	others: bpfilter.h, NBPFILTER
+ *	FreeBSD4: bpf.h, NBPF
+ *	solution:
+ *		#if defined(__FreeBSD__) && __FreeBSD__ >= 4
+ *		#include "bpf.h"
+ *		#define NBPFILTER	NBPF
+ *		#else
+ *		#include "bpfilter.h"
+ *		#endif
+ *
+ * - protosw for IPv4 (sys/netinet)
+ *	FreeBSD4: struct ipprotosw in netinet/ipprotosw.h
+ *	others: struct protosw in sys/protosw.h
+ *
+ * - protosw in general.
+ *	NetBSD 1.5 has extra member for ipfilter (netbsd-current dropped
+ *	it so it will go away in 1.6).
+ *	NetBSD 1.5 requires PR_LISTEN flag bit with protocols that permit
+ *	listen/accept (like tcp).
+ *
+ * - header files with defopt (opt_xx.h)
+ *	FreeBSD3: opt_{inet,ipsec,ip6fw,altq}.h
+ *	FreeBSD4: opt_{inet,inet6,ipsec,ip6fw,altq}.h
+ *	NetBSD: opt_{inet,ipsec,altq}.h
+ *	others: does not use defopt
+ *
+ * - IN_MULTICAST/IN_CLASS[A-D] macro.
+ *	OpenBSD and NetBSD: net endian (kernel) or host endian (userland)
+ *	others: always host endian
+ *
+ * - (m->m_flags & M_EXT) != 0 does *not* mean that the max data length of
+ *   the mbuf == MCLBYTES.
+ *
+ * - sys/kern/uipc_mbuf.c:m_dup()
+ *	freebsd[34]: copies the whole mbuf chain.
+ *	netbsd: similar arg with m_copym().
+ *	others: no m_dup().
+ *
+ * - ifa_refcnt (struct ifaddr) management (IFAREF/IFAFREE).
+ *	NetBSD 1.5: always use IFAREF whenever reference gets added.
+ *		always use IFAFREE whenever reference gets freed.
+ *		IFAFREE frees ifaddr when ifa_refcnt reaches 0.
+ *	others: do not increase refcnt for ifp->if_addrlist and in_ifaddr.
+ *		use IFAFREE once when ifaddr is disconnected from
+ *		ifp->if_addrlist and in_ifaddr.  IFAFREE frees ifaddr when
+ *		ifa_refcnt goes negative.  in KAME environment, IFAREF is
+ *		provided as a compatibility wrapper (use it instead of
+ *		ifa_refcnt++ to reduce #ifdef).
+ *
+ * - ifnet.if_lastchange
+ *	freebsd, bsdi, netbsd-current (jun 14 2001-),
+ *	openbsd-current (jun 15 2001-): updated only when IFF_UP changes.
+ *		(RFC1573 ifLastChange interpretation)
+ *	netbsd151, openbsd29: updated whenever packets go through the interface.
+ *		(4.4BSD interpretation)
+ *
+ * - kernel compilation options ("options HOGE" in kernel config file)
+ *	freebsd4: sys/conf/options has to have mapping between option
+ *		and a header file (opt_hoge.h).
+ *	netbsd: by default, -DHOGE will go into
+ *		sys/arch/foo/compile/BAR/Makefile.
+ *		if you define mapping in sys/conf/files, you can create
+ *		a header file like opt_hoge.h to help make dependencies.
+ *	bsdi/openbsd: always use -DHOGE in Makefile.  there's no need/way
+ *		to have opt_hoge.h.
+ *
+ *	therefore, opt_hoge.h is mandatory on freebsd4 only.
+ *
+ * - MALLOC() macro
+ *	Use it only if the size of the allocation is constant.
+ *	When we do NOT collect statistics about kernel memory usage, the result
+ *	of macro expansion contains a large set of condition branches.  If the
+ *	size is not constant, compilation optimization cannot be applied, and
+ *	a bunch of the large branch will be embedded in the kernel code.
+ *
+ * - M_COPY_PKTHDR
+ *	openbsd30: M_COPY_PKTHDR is deprecated.  use M_MOVE_PKTHDR or
+ *		M_DUP_PKTHDR, depending on how you want to handle m_tag.
+ *	others: M_COPY_PKTHDR is available as usual.

+ * Compressed packet format:

+ * The first octet contains the packet type (top 3 bits), TCP
+ * 'push' bit, and flags that indicate which of the 4 TCP sequence
+ * numbers have changed (bottom 5 bits).  The next octet is a
+ * conversation number that associates a saved IP/TCP header with
+ * the compressed packet.  The next two octets are the TCP checksum
+ * from the original datagram.  The next 0 to 15 octets are
+ * sequence number changes, one change per bit set in the header
+ * (there may be no changes and there are two special cases where
+ * the receiver implicitly knows what changed -- see below).
+ *
+ * There are 5 numbers which can change (they are always inserted
+ * in the following order): TCP urgent pointer, window,
+ * acknowledgement, sequence number and IP ID.  (The urgent pointer
+ * is different from the others in that its value is sent, not the
+ * change in value.)  Since typical use of SLIP links is biased
+ * toward small packets (see comments on MTU/MSS below), changes
+ * use a variable length coding with one octet for numbers in the
+ * range 1 - 255 and 3 octets (0, MSB, LSB) for numbers in the
+ * range 256 - 65535 or 0.  (If the change in sequence number or

+ * control flags set); uncompressed TCP (a normal IP/TCP packet but
+ * with the 8-bit protocol field replaced by an 8-bit connection id --
+ * this type of packet syncs the sender & receiver); and compressed
+ * TCP (described above).
+ *
+ * LSB of 4-bit field is TCP "PUSH" bit (a worthless anachronism) and
+ * is logically part of the 4-bit "changes" field that follows.  Top
+ * three bits are actual packet type.  For backward compatibility

+     The 'zlib' compression library provides in-memory compression and

+  data.  This version of the library supports only one compression method
+  (deflation) but other algorithms may be added later and will have the same
+  stream interface.
+
+     For compression the application must provide the output buffer and
+  may optionally provide the input buffer for optimization. For decompression,
+  the application must provide the input buffer and may optionally provide
+  the output buffer for optimization.
+
+     Compression can be done in a single step if the buffers are large
+  enough (for example if an input file is mmap'ed), or can be done by
+  repeated calls of the compression function.  In the latter case, the
+  application must provide more input and/or consume the output
+  (providing more output space) before each call.
+
+     The library does not install any signal handler. It is recommended to
+  add at least a handler for SIGSEGV when decompressing; the library checks
+  the consistency of the input data whenever possible but may go nuts
+  for some forms of corrupted input.

+    processing will resume at this point for the next call of deflate().
+
+  - Provide more output starting at next_out and update next_out and avail_out
+    accordingly. This action is forced if the parameter flush is non zero.
+    Forcing flush frequently degrades the compression ratio, so this parameter
+    should be set only when necessary (in interactive applications).
+    Some output may be provided even if flush is not set.
+
+  Before the call of deflate(), the application should ensure that at least
+  one of the actions is possible, by providing more input and/or consuming
+  more output, and updating avail_in or avail_out accordingly; avail_out
+  should never be zero before the call. The application can consume the
+  compressed output when it wants, for example when the output buffer is full
+  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
+  and with zero avail_out, it must be called again after making room in the
+  output buffer because there might be more output pending.
+
+    If the parameter flush is set to Z_PARTIAL_FLUSH, the current compression
+  block is terminated and flushed to the output buffer so that the
+  decompressor can get all input data available so far. For method 9, a future
+  variant on method 8, the current block will be flushed but not terminated.
+  Z_SYNC_FLUSH has the same effect as partial flush except that the compressed
+  output is byte aligned (the compressor can clear its internal bit buffer)
+  and the current block is always terminated; this can be useful if the
+  compressor has to be restarted from scratch after an interruption (in which
+  case the internal state of the compressor may be lost).
+    If flush is set to Z_FULL_FLUSH, the compression block is terminated, a
+  special marker is output and the compression dictionary is discarded; this
+  is useful to allow the decompressor to synchronize if one compressed block
+  has been damaged (see inflateSync below).  Flushing degrades compression and
+  so should be used only when necessary.  Using Z_FULL_FLUSH too often can
+  seriously degrade the compression. If deflate returns with avail_out == 0,
+  this function must be called again with the same value of the flush
+  parameter and more output space (updated avail_out), until the flush is
+  complete (deflate returns with non-zero avail_out).
+
+    If the parameter flush is set to Z_PACKET_FLUSH, the compression
+  block is terminated, and a zero-length stored block is output,
+  omitting the length bytes (the effect of this is that the 3-bit type
+  code 000 for a stored block is output, and the output is then
+  byte-aligned).  This is designed for use at the end of a PPP packet.
+
+    If the parameter flush is set to Z_FINISH, pending input is processed,
+  pending output is flushed and deflate returns with Z_STREAM_END if there
+  was enough output space; if deflate returns with Z_OK, this function must be
+  called again with Z_FINISH and more output space (updated avail_out) but no

+  Z_STREAM_END, then it must be called again as described above.
+

+  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
+  binary. This field is only for information purposes and does not affect

+
+     The method parameter is the compression method. It must be Z_DEFLATED in
+   this version of the library. (Method 9 will allow a 64K history buffer and
+   partial block flushes.)
+
+     The windowBits parameter is the base two logarithm of the window size
+   (the size of the history buffer).  It should be in the range 8..15 for this
+   version of the library (the value 16 will be allowed for method 9). Larger
+   values of this parameter result in better compression at the expense of
+   memory usage. The default value is 15 if deflateInit is used instead.
+
+     The memLevel parameter specifies how much memory should be allocated
+   for the internal compression state. memLevel=1 uses minimum memory but
+   is slow and reduces compression ratio; memLevel=9 uses maximum memory
+   for optimal speed. The default value is 8. See zconf.h for total memory
+   usage as a function of windowBits and memLevel.
+
+     The strategy parameter is used to tune the compression algorithm. Use the
+   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
+   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
+   string match).  Filtered data consists mostly of small values with a
+   somewhat random distribution. In this case, the compression algorithm is
+   tuned to compress them better. The effect of Z_FILTERED is to force more
+   Huffman coding and less string matching; it is somewhat intermediate
+   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
+   the compression ratio but not the correctness of the compressed output even
+   if it is not set appropriately.
+
+     If next_in is not null, the library will use this buffer to hold also
+   some history information; the buffer must either hold the entire input
+   data, or have at least 1<<(windowBits+1) bytes and be writable. If next_in
+   is null, the library will allocate its own history buffer (and leave next_in
+   null). next_out need not be provided here but must be provided by the

+
+     If the history buffer is provided by the application, next_in must
+   must never be changed by the application since the compressor maintains

+ * if you trust the remote host to restrict these ports.
+ *
+ * The default range of ports and the high range can be changed by

+ * Changing those values has bad security implications if you are

+ * Overall structure of dummynet (with WF2Q+):
+
+In dummynet, packets are selected with the firewall rules, and passed
+to two different objects: PIPE or QUEUE.
+
+A QUEUE is just a queue with configurable size and queue management
+policy. It is also associated with a mask (to discriminate among
+different flows), a weight (used to give different shares of the
+bandwidth to different flows) and a "pipe", which essentially
+supplies the transmit clock for all queues associated with that
+pipe.
+
+A PIPE emulates a fixed-bandwidth link, whose bandwidth is
+configurable.  The "clock" for a pipe can come from either an
+internal timer, or from the transmit interrupt of an interface.
+A pipe is also associated with one (or more, if masks are used)
+queue, where all packets for that pipe are stored.
+
+The bandwidth available on the pipe is shared by the queues
+associated with that pipe (only one in case the packet is sent
+to a PIPE) according to the WF2Q+ scheduling algorithm and the
+configured weights.
+
+In general, incoming packets are stored in the appropriate queue,
+which is then placed into one of a few heaps managed by a scheduler
+to decide when the packet should be extracted.
+The scheduler (a function called dummynet()) is run at every timer
+tick, and grabs queues from the head of the heaps when they are
+ready for processing.
+
+There are three data structures definining a pipe and associated queues:
+
+ + dn_pipe, which contains the main configuration parameters related
+   to delay and bandwidth;
+ + dn_flow_set, which contains WF2Q+ configuration, flow
+   masks, plr and RED configuration;
+ + dn_flow_queue, which is the per-flow queue (containing the packets)
+
+Multiple dn_flow_set can be linked to the same pipe, and multiple
+dn_flow_queue can be linked to the same dn_flow_set.
+All data structures are linked in a linear list which is used for
+housekeeping purposes.
+
+During configuration, we create and initialize the dn_flow_set
+and dn_pipe structures (a dn_pipe also contains a dn_flow_set).
+
+At runtime: packets are sent to the appropriate dn_flow_set (either
+WFQ ones, or the one embedded in the dn_pipe for fixed-rate flows),
+which in turn dispatches them to the appropriate dn_flow_queue
+(created dynamically according to the masks).
+
+The transmit clock for fixed rate flows (ready_event()) selects the
+dn_flow_queue to be used to transmit the next packet. For WF2Q,
+wfq_ready_event() extract a pipe which in turn selects the right
+flow using a number of heaps defined into the pipe itself.
+

+ * The TCPT_REXMT timer is used to force retransmissions.
+ * The TCP has the TCPT_REXMT timer set whenever segments
+ * have been sent for which ACKs are expected but not yet
+ * received.  If an ACK is received which advances tp->snd_una,
+ * then the retransmit timer is cleared (if there are no more
+ * outstanding segments) or reset to the base value (if there
+ * are more ACKs expected).  Whenever the retransmit timer goes off,
+ * we retransmit one unacknowledged segment, and do a backoff
+ * on the retransmit timer.
+ *
+ * The TCPT_PERSIST timer is used to keep window size information
+ * flowing even if the window goes shut.  If all previous transmissions
+ * have been acknowledged (so that there are no retransmissions in progress),
+ * and the window is too small to bother sending anything, then we start
+ * the TCPT_PERSIST timer.  When it expires, if the window is nonzero,
+ * we go to transmit state.  Otherwise, at intervals send a single byte
+ * into the peer's window to force him to update our window information.
+ * We do this at most as often as TCPT_PERSMIN time intervals,
+ * but no more frequently than the current estimate of round-trip
+ * packet time.  The TCPT_PERSIST timer is cleared whenever we receive
+ * a window update from the peer.
+ *
+ * The TCPT_KEEP timer is used to keep connections alive.  If an
+ * connection is idle (no segments received) for TCPTV_KEEP_INIT amount of time,
+ * but not yet established, then we drop the connection.  Once the connection
+ * is established, if the connection is idle for TCPTV_KEEP_IDLE time
+ * (and keepalives have been enabled on the socket), we begin to probe
+ * the connection.  We force the peer to send us a segment by sending:
+ *	<SEQ=SND.UNA-1><ACK=RCV.NXT><CTL=ACK>
+ * This segment is (deliberately) outside the window, and should elicit
+ * an ack segment in response from the peer.  If, despite the TCPT_KEEP
+ * initiated segments we cannot elicit a response from a peer in TCPT_MAXIDLE
+ * amount of time probing, then we drop the connection.

+ * The SPPT_REXMT timer is used to force retransmissions.
+ * The SPP has the SPPT_REXMT timer set whenever segments
+ * have been sent for which ACKs are expected but not yet
+ * received.  If an ACK is received which advances tp->snd_una,
+ * then the retransmit timer is cleared (if there are no more
+ * outstanding segments) or reset to the base value (if there
+ * are more ACKs expected).  Whenever the retransmit timer goes off,
+ * we retransmit one unacknowledged segment, and do a backoff
+ * on the retransmit timer.
+ *
+ * The SPPT_PERSIST timer is used to keep window size information
+ * flowing even if the window goes shut.  If all previous transmissions
+ * have been acknowledged (so that there are no retransmissions in progress),
+ * and the window is too small to bother sending anything, then we start
+ * the SPPT_PERSIST timer.  When it expires, if the window is nonzero,
+ * we go to transmit state.  Otherwise, at intervals send a single byte
+ * into the peer's window to force him to update our window information.
+ * We do this at most as often as SPPT_PERSMIN time intervals,
+ * but no more frequently than the current estimate of round-trip
+ * packet time.  The SPPT_PERSIST timer is cleared whenever we receive
+ * a window update from the peer.
+ *
+ * The SPPT_KEEP timer is used to keep connections alive.  If an
+ * connection is idle (no segments received) for SPPTV_KEEP amount of time,
+ * but not yet established, then we drop the connection.  If the connection
+ * is established, then we force the peer to send us a segment by sending:
+ *	<SEQ=SND.UNA-1><ACK=RCV.NXT><CTL=ACK>
+ * This segment is (deliberately) outside the window, and should elicit
+ * an ack segment in response from the peer.  If, despite the SPPT_KEEP
+ * initiated segments we cannot elicit a response from a peer in SPPT_MAXIDLE
+ * amount of time, then we drop the connection.
